Rioting has spread across London on a third night of violence, with unrest flaring up in other English cities. An extra 1,700 police officers were deployed in London, where shops were looted and buildings were set alight.

Birmingham, Liverpool, Manchester, Nottingham and Bristol saw violence. The prime minister has belatedly returned early from his holiday to discuss the unrest, which first flared on Saturday after a peaceful protest in Tottenham over the fatal shooting of a man by police. At least 334 people have been arrested and 69 charged following the riots across London over the past three days, Scotland Yard has said.
